Product Description
CMT 690.009 Profile Knives for Insert Shaper System are a precision-matched pair of alloyed steel shaper knives sized 1-37/64 in. x 5/32 in. (40x4mm), designed for use with CMT insert cutter heads in the 692 series. These profile knives bring a specific molding contour to spindle moulders, profile and edging machines, and moulders - making them a dependable choice for cabinet door making, frame and panel work, and edge profiling on hardwood, softwood, MDF, and chipboard. Sold as a pair of 2 knives, the 690.009 is part of CMT's broad variety of profile knife options for their universal cutter head system, giving woodworkers a consistent and repeatable result across production runs and custom millwork projects.
Key Features
- Alloyed steel construction - delivers long-lasting performance and edge retention, reducing the frequency of knife changes during heavy production use on hardwood, softwood, MDF, and chipboard.
- 1-37/64 in. cutting height (40mm) - provides a substantial profile reach, making these knives well suited for molding, edge profiling, and decorative frame work where a full profile cut is needed in a single pass.
- 5/32 in. (4mm) knife thickness - engineered to fit securely within compatible insert cutter heads, ensuring stable seating and vibration-free cutting for smooth surface finishes.
- Sold as a matched pair (2 knives) - both knives are ground to the same profile, so the cutter head stays balanced and delivers uniform results throughout the cut.
- Compatible with CMT 692 series cutter heads and other insert shaper systems accepting 40mm knives - maximizes versatility across different machines without requiring a dedicated proprietary tool body.
- Part of a wide variety of profile knives for the universal cutter head system - allows woodworkers to swap profiles quickly using the same cutter head body, reducing tooling investment and changeover time.
Why This Product
- Woodworkers who already own a CMT 692 series cutter head can expand their profile library simply by swapping knife pairs - no need to purchase additional cutter head bodies for each new molding profile.
- The alloyed steel material used in these knives supports long-lasting performance across demanding materials including hardwood, MDF, and chipboard, making them a practical choice for both production shops and custom woodworking environments.
- At 40x4mm, these knives fit a widely accepted insert shaper knife format, meaning they can be used with compatible cutter heads beyond the CMT 692 series - giving users flexibility across different machines in a multi-machine shop.
- Buying profile knives as a matched pair ensures the cutter head remains properly balanced, which directly contributes to a cleaner surface finish and reduced tearout on finished molding and profiled edges.
